AUTOMATlCALLY-ANCHORING EXCAVATOR AND CONVEYER- Specification of Letters Patent.

Patented May 29, 1906.

Application filed July 22,1905. Sane-1N0 270,760.

age and which can be moved from station to' station on the plat or tract to be excavated without dismantling; also, to provide an excavator and conveyer which can be readily anchored u onthe plat of ground to be excavated an there'employe'd to excavate such plat up to the. edge thereof without shifting the anchoragethat is to say, an object of the invention is to provide means for excavating up to the line on which the machine is set.

Another object is to so construct and arrange the anchorage and conveying-hoist as to leave the space at the edge of the plat to operations. I

A further object is to provide. an effective anchorage of minimum weight, thus avoiding inconvenience in moving from place to place.

T1 is invention includes an anchorage placed rearwardly of the conveying-hoist and to which said hoist is connected by pivoted thrust-beams of considerable length-twenty feet, more or less, for instance-at the sides. of the machine, respectively, thus allowing the anchorage to be placed entirely inside the property-line of the lat of ground to be excavated, while the rum of the conveyinge hoist may extend over the property-line, said drum being movably mounted on a shaft and cross-beam which connect the free ends of said thrust-beams. The drum is mounted to move up and down and also transversely of the anchorage in order that the dig er and scraper may be drawn up a slanting p atform or bridge or hoisted at the drum to any desired height for loading wagons or railroad flat-cars with the material excavated from any por-v tion of the plat covered by the anchorage. Preferably two anchorages and conveyinghoists or traction members are provided for each excavating plant, one being set at each side of the plat of ground to be excavated,

ee for excavating and loading 7 the plow and scraper being operable from one to the other.

The invention also embraces a novel form of excavating device provided with pivoted plows and scrapers and in which some of the tools are so arranged as to automatically loosen and convey the earth when 0 erated in one direction and to automatica ly free themselves from the ground on return movement, while others 0 said pivoted tools are arranged to free themselves when moving in said one direction and to operate at the return movement.

Preferably the thrust-beams which carry the cross-beam and shaft for the drum of the conveying-hoist are triangular in end elevation, each endof the anchorage being formed of a triangular frame and said frames beingconnected by cross beams at their tops, thus leaving the space between the end frames and below the drum free from any obstruction,

the object of tbis'being to allow the excavating device to loosen and remove the surface of the ground directly to the property-line without placing any portion of the machin on adjoining property. 7

, The drums may be'respectively operated by any suitable motor carried by the frames or resting on the ground and connected with the drums, respectively, by means of frictionclutches, belts, or other reversing means.

The end frames are preferably made of triangular form order to allow a large upand-downmovement of the drum' and to afford the 'best anchorage to resist the thrust of the conveying-drum at different heights above the ound-level. The frame may be constructe of wood or metal and its parts bolted to ether, so as to be conveniently knocked down and erected again.

Another object of the invention is to provide an anchorage having a large ground plan Without obstructing much of the groundspace, so that the machine can be anchored with anchor-stakes or like anchors that may be easily removed when it is desired to move the structure.

Another object of the invention is to so construct the machine that the stress on the anchorage will be approximately horizontal, and this, together with the large ground plan of the anchorage, causes the stress component tending to raise the anchors to be very slight.

foo

Another object of the invention is to provide an excavator of superior character for excavating canals and making long cuts where the width of the cut is comparatively cred intothe cut as the work proceeds until anchorage-frame at 10.

' tween them, connecte the out has been made to the required depth at that station, and then the anchorage can be moved along the proposed cut to the next station, and so on until the work is comleted. For this purpose each anchorageame may be provided with truck-wheels.

The accompanying drawings illustrate the invention.

(1 designates connections for moving the slide along the cross-beam 7 thus to shift the drum 4 along the shaft. k

Pulleys 11 and belts 12 serve as means to -Figure 1 is an elevation of a complete ex-.

transmitting means may be employed. In the arrangement shown belt I) is straight and belt 0 is crossed, forming with the shift 14, a

wellknown reversible system.

15 is an adjusting-pulley mounted, by means of a slide 16,'carried by a swinging beam 17, pivoted at 19 to frame 1. Said adjusting-pulley is connected to the motor by belt (1. for raising and lowering'the adj misting-pulley to tighten and loosen the belts. By this arrangement the belts may be kept tight at all positions of the hoisting-drum.

' 20 designates braces on the triangular frame 1 to stifl'en the same at the top ,of the frame 1, where they will not be inthe way. At the top of the frame and extending rearwardly are beams 21 which support at their ends block and tackle 22 23. The tackles 23 are broken in the view to avoid confusion; but it is to be understood they may be secured to thrust-beams 9 and 9 or fastened in sired height.

On the corners of the anchorage are mounted anchor-stakes 25, one at each corner, which serve to hold the trian ular frame 1 stationary on the ground. Re erring to Fig. 10, 26 is a block fastened to the sill 27 of the anchorage and provided with .a slot 28, through which passes the anchor-plate 29, which has in it a series of holes 30 for the reception of a pin 31, that passes underneath plate 32 for the pur ose of keeping the anchor-stakes extende the desired distance below the framework ofv the anchorage. anchor-plate 29 is formed in a fish-tail 33 at its lower end to facilitate sinking into the ground. Fastened to it at the'lower end at right an les is a second fish-tail late 34 to increase t e stability of the anciiorage. The anchor-stakes are of considerable lengthfso that the lower end thereof may be sunk by the weight of the anchora e to a considerable l depth in the earth and a low enough of the anchor-stakes to project above the ground, so that; if necessary, the anchorage-frame may remain at or be raised to a considerable height above the ground and there be supported on the anchor-stakes.

On the side of the anchorage-frame I have shown posts 35, which serve to hold hingebutts'36. Frame 37 of truck 38 has on it companion hinge-butts 36, which are adapted to fit the butts 36 and to be held in place thereon by removable hinge-bolts 39.

18 is a line connected with slide 16' The,

stored to the osition shown in the drawings,

and the truc wheels removed, whereupon the anchor-stakes will sink into the ground under the Weight of the anchorage.

' It is to be noted that the anchorages 1 are each provided with two legs h i, constructed and arranged to straddle the ground to be ex-' cavated, leaving the surface space between the legs open and free for the o eration of the excavating device, and that t e feet of said legs are parallel with each other and are long and narrow, having small lateral extension and considerable extension front and rear, so as to aiiord large frictional footing with or without the anchor-stakes 25.

. Between the two conveying-hoists and at tached thereto by the cable'3 is the excavating device comprising a digger and scraper 2,

, which is arranged to be reciprocated over the ground between the hoists and is shown in enlarged detail in Figs. 7, 8, and 9. Said digger and scraper is provided with plows 40 40, the shanks 41 41 of which are pivoted on shafts 42 42, respectively, above the lows. The plows 4O and 40" are reversely an inde pendentl y mounted, so that when the scrapershell 50 moves in one direction the plows 40 will come into operative position and the plows 40 will be t and vice versa on a reverse movement of said shell, the action being automatic, as herein-- movement of the'scra e'r'is limited in the same manner as that o the plowsby stops formed by beams 48 and 49. Plows 40 40, with their mountings, and scraper 45, with its mountings, are all carried inside a shell 50,-

closed'at the sides and open at front and 'back, which serves as a retainer to hold the excavations as they are conveyed off the ground.v In Fig. 7 the excavating device is shown with the plows and scraper in operative position while said device is being drawn in thedirection indicated by the arrow. On the back side of" thetools 40 and (viz., the plows and scrapers) are heels 5], which catch into the soil on the forward movement and throw the tools into the osition shown in full lines.

rown out of such position,

When the excavator is drawn back, the tools automatically throw into the position shown in dotted lines and run on the heels 51. i On the sides and bottom of the scraper-shell 50 are runners 52, which support the shell while the excavator isbeing drawn over the ground. Bars 53 extend across the ends'of the shell 50 and at their ends are turned into eyes 54, to which cable 3 is attached.

In practice to 'set the machine, the frame being erected and being supported off the ground-surface by the truck-wheels 38, the

anchor-stakes 20 are then lowered to the surface of the ground. The pins 31 are then placed in the appropriateholes 30 in the anchor-stakes, and the wheels 38 are then removed. Thereu on the. anchor-stakes are. sunk into the soi by the weight of the frame. By alternately operating the motors 13 the scraper and dig er is conveyed to and fro across the plat, 5111s excavating and conveying material to'one side underneath the conveying-drum 4 of the hoist. As the .work proceeds the conveying-drums will from time to time be simultaneously shifted along shafts 5 b digger an scraper to shift to excavate new ground until the whole area between the two anchorages has beenexcavated tothe required depth.

on the cross-beam 7 of the thrust-frame to support the shaft 5, along which the boxes slide, so as to support the shaft close to the drum and intermediately of the boxes 8 therefor. The hangers and boxes are conventionally shown and may beof any suitable form. l

.- When the excavation between the legs h '1', of frames 1 has been completed, the truckwheels ,may then be replaced and adjusted to support the anchorage and frame, which will then be moved to where the anchor-stakes will again be set, and the excavation continued, as before. Thus by successive movements of the anchorages the work may be continued over any extent of territory. The distance between the anchorages may be as lon as desired'within practical limits, thus ma g the travel of the excavator as long as possible, and thereby reducing the expendiple raisingof the free ends of the thrust-beams.

adopted without avoiding the invention.

In Fig. 14 a sloping bridge 66 is shown in position for loading a flat-car. (Not shown.) It is to be understood that the width, he' ht,

' and length of the bridge may'vary accor ing to requirements.

The plows and scraper are detachable by removing their respective shafts, and in some cases the plows 40 and 40 may be used with out the scraper, and in other cases one set of plows 40 or 40 may be used alone or with the scraper only. The plows 40 and 40 are mounted reversely of each other, so that when the, digger and scraper moves in one direction plows 4O operate and plows 40 are inoperative, and vice versa.

' By means stated the reversely-pivoted tools are caused to operate on the ground in alternation at the alternate reverse move ments of the digger' and scraper.
